Matias FK318S USB Wired Aluminum Keyboard with Numeric Keypad and 2x USB Ports.

Features:

• Perfect to use with external speakers, this volume dial gives you a finer volume control than you’d get from pressing volume keys. The dial offers 64 volume levels, as opposed to the 16 you get with volume keys. That’s 4 times the precision!
• The Matias FK318S is compatible with Mac OS X all the back to version 10.6.8 (Snow Leopard). This can be a lifesaver if you are running legacy software on older systems.
• This keyboard features a built-in hub that is great for connecting your favorite wired mouse or dongle, with a second port available for plugging in flash drives or other devices.
